Abstract
Background: Inflammation and oxidative stress are key players in lung injury stemming from cardiac ischemia (LISCI). Cannabidiol (CBD) demonstrates tissue-protective properties through its antioxidant, anti-inflammatory, and anti-apoptotic characteristics. This study aims to assess the preventive (p-CBD) and therapeutic (t-CBD) effects of CBD on LISCI.
Methods: Forty male Wistar Albino rats were divided into four groups: control (CON), LISCI, p-CBD, and t-CBD. The left anterior descending coronary artery was ligated for 30 min of ischemia followed by 30 min of reperfusion. Lung tissues were then extracted for histopathological, immunohistochemical, genetic, and biochemical analyses.
Results: Histopathologically, marked hyperemia, increased septal tissue thickness, and inflammatory cell infiltrations were observed in the lung tissues of the LISCI group. Spectrophotometrically, total oxidant status and oxidative stress index levels were elevated, while total antioxidant status levels were decreased. Immunohistochemically, expressions of cyclooxygenase-1 (COX1), granulocyte colony-stimulating factor (GCSF), interleukin-6 (IL6) were increased. In genetic analyses, PERK and CHOP expressions were increased, whereas Nuclear factor erythroid 2-related factor 2 (NRF2) and B-cell leukemia/lymphoma 2 protein (BCL2) expressions were decreased. These parameters were alleviated by both prophylactic and therapeutic CBD treatment protocols.
Conclusion: In LISCI-induced damage, both endoplasmic reticulum and mitochondrial stress, along with oxidative and inflammatory markers, were triggered, resulting in lung cell damage. However, both p-CBD and t-CBD treatments effectively reversed these mechanisms, normalizing all histopathological, biochemical, and PCR parameters.
期刊介绍：
The journal Immunopharmacology and Immunotoxicology is devoted to pre-clinical and clinical drug discovery and development targeting the immune system. Research related to the immunoregulatory effects of various compounds, including small-molecule drugs and biologics, on immunocompetent cells and immune responses, as well as the immunotoxicity exerted by xenobiotics and drugs. Only research that describe the mechanisms of specific compounds (not extracts) is of interest to the journal.
The journal will prioritise preclinical and clinical studies on immunotherapy of disorders such as chronic inflammation, allergy, autoimmunity, cancer etc. The effects of small-drugs, vaccines and biologics against central immunological targets as well as cell-based therapy, including dendritic cell therapy, T cell adoptive transfer and stem cell therapy, are topics of particular interest. Publications pointing towards potential new drug targets within the immune system or novel technology for immunopharmacological drug development are also welcome.
With an immunoscience focus on drug development, immunotherapy and toxicology, the journal will cover areas such as infection, allergy, inflammation, tumor immunology, degenerative disorders, immunodeficiencies, neurology, atherosclerosis and more.
Immunopharmacology and Immunotoxicology will accept original manuscripts, brief communications, commentaries, mini-reviews, reviews, clinical trials and clinical cases, on the condition that the results reported are based on original, clinical, or basic research that has not been published elsewhere in any journal in any language (except in abstract form relating to paper communicated to scientific meetings and symposiums).
